Frozen modifiers stay in stack, but do not affect anything until you click Unfreeze or Update. If you do not want to freeze some modifiers in stack, just turn off “Display modifier in viewport” for them before clicking Freeze.įrozen modifier marked by (F) at the begin of its name. You will see the last result of modifiers’ work, how it was before you clicked Freeze.Īll visible modifiers of active object will be frozen. Turns off visible modifiers’ interactivity. Also you can press Ctrl+A and see new items at the bottom of Apply menu: Freeze, Unfreeze and Update Frozen Modifiers. You will see new buttons at the top of Modifiers panel: Freeze, Remove, Unfreeze and Update. This is not a perfect solution, but it works, and allows you to work with “modifier-heavy” objects relatively comfortable. But in future you can “Unfreeze” these modifiers, if you need, or just change their parameters and click “Update” to recalculate mesh. You can “Freeze” some modifiers in stack, as if you clicked Apply for them, and they will not be recalculated every frame. Modifreeze works like a temporary “Apply” for modifiers. So, Blender can work much more faster, if you manually update mesh geometry when you really need this. Only if you change parameters of modifier (or move a boolean target, for example), you need to recalculate mesh geometry. Usually there is no any changes in existing geometry. In fact, you don’t really need to recalculate all modifiers every time for every frame. How can Modifreeze addon help in this case? So, before calculate a new boolean operation, Blender needs to recalculate all previous boolean, bevel, etc. This happens because this sci-fi style thing is result of very many boolean, bevel, etc. Beginning with 30:47 we can see extremely slow viewport updating. (For example of cool non-destructive modeling, see this awesome video by Chris Prenninger.) Non-destructive techniques works fine for few simple objects, but when you have a lot of parametric objects that uses a lot of modifiers, expecially for boolean operations, this become a problem.įor example, look at the final of another awesome video by Cédric Lepiller. This is critical for parametric non-destructive modeling techniques that become very popular now. This sometimes leads to very low FPS (frames per second) in Blender viewport. In some cases every time, for every new frame, Blender recalculates effect of every modifier in stack of every object. It happens when you use too many modifiers. I created this addon because sometimes Blender viewport updates very slowly. You also can remove “frozen” modifiers or “update” it. Modifreeze is a small addon that gives you ability to “freeze” or “unfreeze” mesh object modifiers. Excuse me for some mistakes in this text, English is not my mother tongue.
